Port103Z STM32F103ZE MCU Full IO Expander JTAG/SWD STM32 Development Board Kit
Descriptions:- Port103Z is a STM32 development board that features a STM32F103ZET6 device as the microcontroller, supports further expansion with various optional accessory boards for your specific application. It is ideal for starting application development with STM32F family.

- Note: Optional accessory boards are NOT included in the price.

1.MCU: STM32F103ZET6 from STMicroelectronics, incorporates the high-performance ARM® Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency in LQFP144 package. The STM32F103ZET6 offers high-speed embedded memories(512KB FLASH, 64KB RAM), 12-bit ADC, 12-bit DAC, I2C, SPI, I2S, SDIO, USART, USB, and CAN.
2.Onboard 3.3V regulator, AMS1117-3.3
3. Power indicator
4. User LEDs: These LEDs are connected to the MCU pin via jumpers, used for indicating IO status or program running status while debugging
5.Reset button
6.User Buttons
7.Joystick, 5 directions
8.8M crystal, enables the MCU run at 72M frequency by frequency multiplication
9. 32.768K crystal, used for internal RTC, also supports clock calibration.
10.Programming interface (JTAG/SWD), onboard 20-pin JTAG/SWD header
11.USB connector, used for establishing USB communication between PC and the STM32 development board
12.USART1 pin header, supports ISP (In-System Programming) through USART1, as well as system signal output
13.IO expander, all the MCU pins are accessible on expansion connectors for further expansion
14.Power input/output header, 5V/3.3V, usually used for power output, or common ground with other user board
15.5V DC power jack
16.Boot modes configuration: jumpers for selecting STM32 boot space
17.Jumper for selecting power supply, powered from 5V DC jack or USB connection
18.USB enable jumper
Short the jumper to enable the PC auto detection while USB connecting
Open the jumper to disable
19.VBAT enable jumper, powered from battery is available via this jumper, an external battery is required
20.VREF jumper
Short the jumper to connect VREF+/VREF- respectively to VCC/GND
Open the jumper to connect VREF+/VREF- to other custom pins via jumper wires
21.User LEDs jumper
Short the jumper to connect to I/Os that used in example code
Open the jumper to connect to other custom pins via jumper wires
22.User Buttons jumper
Short the jumper to connect to I/Os that used in example code
Open the jumper to connect to other custom pins via jumper wires
23.Joystick jumper
Short the jumper to connect to I/Os that used in example code
Open the jumper to connect to other custom pins via jumper wires

Note:
- Accessory board and programmer/debugger in the photos are NOT included in the price.
- Port103Z supports programming through USART port without programmer.
- Port103Z provides JTAG/SWD debugging interface, yet does NOT integrate any debugging function, a debugger is required
